One form of guard member is best illustrated in Figure 2 and comprises a. body portion 15 formed of sheet stock having up- `turned end walls 16 and 17. YThe end wall A17 is herein shown as being provided with a finger member V18vvhich is arranged to overlie and press upon the pin shank when extending through the openings 19 in these The body portion 15 of this guard member is preferably slit'as at 2O forming a latch member 21 which is raised from the stock of this body, the latch having an intuined engaging abutment end 22 whichyis arranged to enter any one of the notches ,13 in the shank and restagainst the abutagainst being inadvertently removed therefrom, and yet may be readily removed upon being rotated on the pin and given an axial movement with reference thereto to permit the latch to be withdrawn therefrom.

The foregoing description is directed solely towardsthe construction illustrated,'but we desire it to be understood that we reserve the privilege of resorting to all the mechanical changes to which the device is susceptifble, the invention being defined and limited only by the terms of the appended claims.

We claim: `v1. In combination a stick pin having a plurality of 'staggered notches in its shank, a guard having a body porton with end walls pierced to receive the shank of said pin and an abutment toV engage any one of the notches in the pin. l

2. In combination with a stick pin having a notched shank a guard having a body portion with end walls pierced to receive the shank of said pin, one of said end walls having an extension arranged to overlie and resiliently engage said pin shank when positioned in the guard, and a retaining spring latch carried by the body to releasably en- Y the latch to engage the same by a relative axial movement of the pin and guard and permitted to be removed from the pin by a relative rotative movement in either direction combined with a withdrawing movement.

4. In combination, a stick pin having a shank with a plurality of abutments staggered about its surface, a guard for said pin having a 1cody portion with end walls pierced to receive said pin shank, one of said end walls having an extension arranged to overlie and resiliently engage said pin shank when positioned in the guard, a spring latch cut and raised from the stock of the body and arranged to yieldingly engage an abutment inthe pin, said abutinents cooperating to permit thelatch to engage the same by a relative axial movement of the guard and pin and permitted to be removed from the pin by a relative rotative movement in either direction 4combined with a withdrawing movement.

5.v In combination a pin stem guard member having spaced Walls with openings to receive the shank of the pin,abutment means on said guard member, a pin ste-ni'member having a shank with spaced abut-ment means about its surface to be engaged by said abutment means on said guard member irrespective of the relative rotative positions ofl said members, said means cooperating to permit said members to be attached by an axial movement in one direction and disengaged only by a combined axial movement and a relative rotative movement in either direction. i

In testimony whereof we aiiix our signatures.
